Abstract
|
|
|
This study was performed to find a relationship between each pattern identification and vascular status using the
second derivative of photoplethysmogram waveform(SDPTG) indices. We analyzed 200 subjects who participated in
stroke preventive examination. We classified the subjects into four groups of pattern identifications; Fire-Heat pattern
(ûýæðñû; FH), Yin Deficiency pattern(ëäúÈñû; YD), Qi Deficiency pattern(ѨúÈñû; QD) and Dampness-Phlegm pattern(ã¥ÓÃñû;
DP) that based on Korean Standard Pattern Identifications for Stroke-¥². We studied a relationship between each
pattern identification and the SDPTG. The total number of the subject group was 200, whereas the groups were divided into four groups; Fire-Heat pattern group(n=49), Yin Deficiency pattern(n=57), Qi Deficiency pattern(n=45), and
Dampness-Phlegm pattern(n=49). b/a ratio was related with age and systolic blood pressure, c/a ratio was associated
with age, systolic blood pressure, fasting blood sugar and Total cholesterol, d/a ratio was affected with age, diastolic
blood pressure, and hypertension, e/a ratio was related with age and sex and SDPTG AI was associated with age. c/a
ratio and d/a ratio were significantly higher in the Fire-Heat group than in the Qi Deficiency group. SDPTG AI was
significantly higher in the Qi Deficiency group than in the Fire-Heat group. The Qi Deficiency group was significantly
older than the Fire-Heat group and the number of hypertension patients was significantly more in the Fire-Heat
group than in the Qi Deficiency group. Through this study, we found out some significant relationships between each
pattern identification group and the SDPTG indices.
